I guess there's no other way to decribe this. It was just a rough day at Birubi. Nothing unusual, common enough to be an ordinary event. Just a part of the natural cycles of the weather and the ocean.
I think sometimes life can feel a bit like this too. There's nothing we can really point to that is out of the ordinary. No 'big thing' happened. In fact the day seemed to be a collection of ordinary things that are just part of the natural cycles of life. Just a rough day.
Just like the beach rough days happen. And so do calm days. And so do those magic good days when you could stay in the ocean all day and just float, soaking up the sun (which is not too hot), the water (which is not too cold) and the gentle rocking of the surf (which is just right). When we have rough days these magic ones seem so far away. But they're not. We just need to get through the rough one first.
